Motion in one dimension, that is East-West or North-South for example, can be analyzed by adding colinear vectors. As was evident in our discussion of displacement, motion is not just restricted to one dimension. In such situations, the two-dimensional vectors were resolved into horizontal and vertical components (one-dimension) to simplify their analysis. We will revisit two-dimensional vectors yet, in the meantime, we will observe how graphs can communicate information to us about the one dimensional nature of the motion of an object. In doing so, we will also introduce (review) the concepts of speed, velocity and acceleration.
The links below, from what I consider to be an excellent Physics educational site, will help you review/understand position-time and velocity-time graphs. When reading through these links, be sure to read through the entire lesson (further links are given at the website itself).
